I signed up for the free version of Duolingo. I didn't like it so didn't continue after a couple of days. I noticed the next month that they charged my credit card $135.59. When I contacted them about this they asked for my username and e-mail address. This transaction shows as being paid from Google Play. I have never given my credit card to Google play so I don't know how they were able to charge my card. They claim they don't have a record of my e-mail address or username. How is it my credit card shows Duolingo-Google play? They won't give me my money back! What a scam!
